    摘要: The present invention relates to compositions and methods to treat and/or prevent biofilms and biofilm related diseases. The invention comprises a nanoparticle carrier (NPC) and at least one therapeutic agent therein. The NPC binds within biofilm and to surfaces at risk for biofilm formation and accumulation while providing local, sustained, enhanced and controlled delivery of the therapeutic agent, when triggered for release. In one embodiment, the NPC comprises pH-responsive elements that allows for specific delivery of the therapeutic agent when the local environment dictates that the agent should be delivered precisely when it is most needed.

    摘要: The present invention provides compositions and methods for providing controllable local delivery of a therapeutic agent to promote bone formation. In certain embodiments, the invention is used as a treatment for a subject with osteoporosis, bone cancer or bone fracture. The invention provides a therapeutic agent that is tethered to a polymer to form a therapeutic-tethered macromer, where the therapeutic agent is controllably released from the conjugate by degradation of the tether. In certain embodiments, the therapeutic agent is an inhibitor of GSK3β. In certain embodiments, the composition of the invention is specifically targeted to a site in need of bone formation.

    摘要: Provided is a method for increasing proliferation of mesenchymal stem cells. The method entails contacting the cells with 6-bromoindirubin-3′-oxime (BIO). This results in robust proliferation and “sternness” in a dose-dependent fashion, as indicated by the gene expression of two stem cell genes: Sox2 and Nanog.
